Applicationfiled January 15, 1912. Serial No. 671,168.

T0 all whom lit may concern Be it known that I, RICHARD W. FUNK,

a citizen of the` United States, residinginA ery of the tire-carryingrim`andthe outer.

periphery of; the telly band1 are provided with interlocking means,adapted to kengage eachother bythe relative rotation of the two partsthrough a`- small/arc.` Opue`or more.,

wedge members interposed between the `tirecarryingrim AandtheIfellyloand are provided for securinglthetire rim` and `felly` in theirpredetermined` operative position. The` removal hof, these wedgespermits the tire-carrying rim y to tbe, released from thev felly bandand, with ;i`ts .tire`,to be removed as a unit Afromfthe wheel.

In the accompanying drawings, which form a part offthis speciiication,Figure 1. lis a side elevation o'fafwheell eguipped with my improveddevice; Eig. 2 isa transverse sectional view lon line llf-"Il of Fig. 1;Fig. 3. isa top view off Fig. Q with th'etire rim removed. l n

Referring to the drawings 'in detail, `the numeral 1 designates a ,wheel'having y a felly 2 upon which is permanentlyy secured the felly band 3about one ledge of which is a turned-up Hange 4 forsllpporting oneasiderof the tirecarrying run-5.A Spaced about.

the outerperiphery of-the "felly, band and permanently secured theretois a pluralityy Vof lugs 6. One side of each,lugfisprovi'dedf with twoparallel faces'? and 8, substantially perpendicular tol the. plane ofthe wheel, anda .third face 9 connecting them` and inclinedto theirplanes. The tire-carrying rim is provided witha corresponding.

number of lugs 10 eXten'ding radially in- 7 8 and 9 and lit closelythereto when in operative position, as illustrated in Fig. 3. Theinterlocking of the two sets of lugs 6 and 10 will obviously prevent anyside movement orl movement in the direction of the airis of the wheelofthe tire-carrying rim with respect to the rest of the wheel.

ForA supporting in a radial direction the side of the tirecarrying rim,opposite to the lange Ll, 'a `number of wedges 11 may be provided whichenter the space between the :telly band and the tire-carrying rim. Thesewedges may be secured in placeby means of a nutlQ ,engaging a boltlpermanently secured to the fel'ly and extending therethrough. The nut 12is provided with a flange 141 whichi's confined within a recess 15in thewedge member by means of a faceplateA 1G, the faced portion of the nutpassing through an opening 17 in the face-plate which is of smallerdiameter than that of the flange 111. Detachment of the wedgestructurefrom the felly is prevented by Vmeans of ashaft 18 secured tothe lower yportlo'n ofthe .wedge member and entering a cavity 19 in thefelly. This shaft passes through a retaining plate 20 which issec'uredfto the `felly by means of staples 21 forced intoV thesame. `Theplate 2O is provided with a1 section 22 bulging slightly awayl fromltheface of the felly, to form a fulcrum for thewedge structure when it isforced home by the engagement of the nut on the bolt, A {lang-e 23 onthe inner eX- rtreinity4 ofthe shaft 1S, which is larger in diameterthan the opening through the plate 20, preventsl the removal of thewedge from the jfelly, but permits much freedom in adjustment. Three ofthese wedge members mayk beused, as `shown in Fig. 1. ln order tocarrythe driving strain when the rotation lof the Awheelis reversed, oneof these -wedgesnis provided withlan eXtra tongue 24,

which is slightly wedge-shaped and projects between onevof the drivinglugs 10-and the driving, plate 25, which is secured to the felly band.

VTo remove the tire-,carrying rim from the wheel, thethree wedges arefirst backed off from thefelly by loosening their nuts and then turneddown out of the way into the position indicated by the dotted lines inFig. 2,1so that the tire-carrying rim may be rotated in a directionrelative to the wheel, indicated bythe arrow in Fig. 8. The lug 10thereby assumes the position shown by the dotted lines in that figure.The entire rim and tire may then be removed as a unit from the felly bya movement substantially parallelto the axis of the wheel. The reversalof this process accomplishes the mounting of the rim upon the wheel.

It is to be noted, as shown in Fig. 2, that the lugs l0 do notcompletely fill the space:

'there is therefore no danger of its collapse from insufficient supportin a radial direction.

Having thus described my invention, l

claim:

l. In a vehicle wheel, a fixed rim, a tirecarrying rim, and means formounting the latter upon the former including a plurality of lockingmembers circumferentially spaced about the periphery of the fixed rimand projecting upwardly therefrom, and a similar number of lockingmembers depending from the inner periphery of said tire-carrying rim andadapted to lock said tire-carrying rim against lateral displacementthrough rotative engagement with said` first-named locking members, cachof the locking members of the fixed rim having three faces opposed tothree faceson a locking member on the tire-carrying rim, their outwardand inward pairs of faces lying in parallel planes substantially atright angles to the plane of the wheel, the intermediate pairs of facesbeing parallel and inclined to the plane ofl the wheel, and means forsupporting'the tire-carrying rim in a radial direction andfor-preventing disengagement of said locking members comprising aplurality of ad- -.justably mounted wedges adapted to seat between saidrims, one of said wedges having an extension adapted to seat between alug on the tire-carrying rim and la lug on the fixed rim, and means forpermanently attaching said wedges to said fixed rim.
